local user rather than forward it to another mail server. By default, this is all configured addresses on
the machine, as well as localhost within the local domain. You may specify any number of domains
or host names separated by commas, or you may provide a full path to a file containing similar
entries. The variables $myhostname and $mydomain may be used to represent those concepts to
Postfix automatically. The ability of Postfix to use such variables throughout its configuration files
makes it easier to maintain a number of Postfix servers with similar configurations. This option
correlates to the mydestination directive.
What trouble to report to the postmaster
Postfix provides the ability to select what types of error messages will be mailed to the designated
postmaster of the mail server. Assuming you have set up a postmaster alias that directs mail to a
real person, Postfix will send reports of all trouble designated here. The available classes are:
bounce
When this option is selected, whenever a message is undeliverable, a bounce message (called
a single bounce message will be sent to the message sender and the local postmaster. For the
sake of privacy, only the headers will be sent to the postmaster. If the first bounce is returned as
undeliverable, a double bounce message will be sent to the postmaster with the entire contents of
the first single bounce message.
2bounce
Causes double bounce messages to be sent to the postmaster.
delay
If the delivery of a message is delayed, the postmaster will receive a notice, along with the headers
of the delayed message.
policy
Notifies the postmaster of messages that were rejected due to an unsolicited commercial email
policy restriction. The complete transcript of the SMTP session is sent.

resource
Informs the postmaster of undelivered mail due to resource problems, such as a queue file write
error.
software
Notifies the postmaster of mail not delivered due to software failures.
This option correlates to the notify_classes directive, and defaults to reporting only problems that
usually indicate a misconfiguration or serious problem (specifically resource and software). In some
